50 day old Gorilla Cookies by Fast Buds growing in a local shops super soil - I am new to this but I feel like this is a nitrogen deficiency - I feed once a week with 2 step, currently feeding about 1/4 strength of flower. Should I up the dosage?

That’s not a nitrogen deficiency. Based on the dark leaves and burning tips it could be a nitrogen excess. Do you know your runoff pH and PPM? Fill out a support for the best help.

I don’t test runoff, maybe I should look into that
Apera and Bluelab both make quality pH and PPM meters. It’s difficult to offer help without understanding where runoff pH and PPM are. Given the appearance of the plant, the nutrients you are using, and the age of the plant, I expect you have a serious pH issue. Possibly PPM problems as well.

Ph in 5.8 Ph out 6.8, may have found a problem

6.8 is on the high end of the range, but it is okay. It tells us that you don’t yet have a salt buildup in the root zone, which is a good thing. A salt buildup will cause a chronically low pH.

Should I lower my ph with what I water, maybe sorb to 5.5 or keep with 5.8 and just monitor runoff ?

It should be between 6.3 and 6.8 if you are in soil.
